HTML5 APIs are examples of DHTML because they utilize multiple technologies to extend functionality. Which technologies are included?

The correct choice accurately identifies the technologies that are commonly associated with DHTML, which is a dynamic form of HTML that allows for more interactive and engaging web applications. HTML5 is the backbone, providing a more flexible structure for web pages. Cascading Style Sheets (CSS) are crucial for styling these pages, allowing for layout and design enhancements that can respond dynamically based on user interaction. JavaScript plays a vital role in enhancing the interactivity by allowing the manipulation of the Document Object Model (DOM), which represents the page structure in memory and can be altered to change the displayed content without reloading the entire page.

This combination of HTML5, CSS, and JavaScript embodies the principles of DHTML, where multiple technologies work together to create dynamic, interactive user experiences. By leveraging these three technologies, developers can build web applications that respond to user input in real-time, resulting in a smoother and more engaging user experience.
